NVIDIA has announced the release of NVIDIA Ising, the first family of open-source AI models designed exclusively to speed up the development of practical quantum computers, in a move that is expected to completely change the high-performance computing landscape. This new AI suite, named after the seminal Ising mathematical model that greatly simplified the scientific understanding of complicated physical systems, attempts to address the most enduring “bottleneck” issues in quantum hardware error correction and processor calibration.
The “fragility” of existing quantum bits, or qubits, continues to hinder the quantum computing industry as it gets ready to reach an anticipated $11 billion by 2030. By positioning AI as the “control plane” or “operating system” for these fragile machines, NVIDIA’s entry into this market turns them into dependable, scalable quantum-GPU systems.

The AI-Powered “Control Plane”
The NVIDIA Ising family is made to enable researchers and businesses to create high-performance AI solutions while keeping complete control over their data and infrastructure. The CEO and founder of NVIDIA, Jensen Huang, asserts that “AI is essential to making quantum computing practical.” AI takes over as the control plane with Ising, converting brittle qubits into scalable and dependable quantum-GPU systems.
Two main technical obstacles are the focus of the suite:
Ising Calibration: From Days to Hours
The process of fine-tuning a quantum processor to guarantee qubits function predictably takes days to hours. This is typically a laborious, manual procedure that can take many days. A visual language model (VLM) that can quickly understand measurements straight from quantum processors is introduced by Ising Calibration. This reduces the time needed from days to a few hours by enabling AI agents to automate ongoing calibration.
Ising Decoding: Speed and Accuracy Breakthroughs
Advances in Accuracy and Speed Error correction may be the biggest obstacle to “useful” quantum computing. Since quantum states are infamously unstable, real-time error correction is computationally costly. Two variations of a 3D convolutional neural network model make up Ising Decoding. These models execute real-time decoding for quantum error correction and are geared for either maximum speed or greatest accuracy.
The framework allows quantum developers to choose between two base models depending on their specific hardware needs:
- Ising-Decoder-SurfaceCode-1-Fast: A streamlined model with roughly 912,000 parameters, optimized for maximum speed.
- Ising-Decoder-SurfaceCode-1-Accurate: A larger model with 1.79 million parameters designed to correct more complex error chains.
Technical projections for these models are ambitious. Using NVIDIA Grace Blackwell (GB300) GPUs and FP8 precision, NVIDIA anticipates the “Fast” model can achieve a decoding speed of 0.11 μs per round. For systems prioritizing precision, the “Accurate” model combined with PyMatching has already demonstrated a 2.25x speedup and a 1.53x improvement in the Logical Error Rate (LER).
According to internal benchmarks, NVIDIA Ising Decoding outperforms the current open-source industry standard, pyMatching, by up to 2.5 times in speed and 3 times in accuracy. Researchers may now handle far larger and more complicated problems that were previously beyond the capabilities of current quantum hardware by increasing the precision and speed of the decoding process.

Global Ecosystem Adoption
Scientific backing for the announcement has grown worldwide. Prominent businesses, educational establishments, and national research facilities have started incorporating Ising into their processes.
Currently, a wide range of partners are using Ising Calibration, including:
- National Labs: Both Fermi and Berkeley’s Advanced Quantum Testbed are national labs.
- Academic Institutions: Harvard John A. Paulson School of Engineering and Applied Sciences, Academia Sinica.
- Industry Leaders: IQM Quantum Computers, Q-CTRL, and Atom Computing lead the industry.
Ising Decoding is also used by Cornell University, Chicago University, Sandia National Laboratories, and Yonsei University in South Korea.

Integration with the NVIDIA Quantum Stack
NVIDIA Ising is intended to supplement and improve NVIDIA’s current quantum-classical ecosystem; it does not exist in a vacuum. The models are easily integrated with both the NVIDIA NVQLink hardware connection and the NVIDIA CUDA-Q software platform. This combination offers a full-stack approach to transform today’s experimental qubits into tomorrow’s accelerated quantum supercomputers by enabling real-time control and error correction.
NVIDIA is offering a “cookbook” of quantum computing procedures and training data in an effort to further reduce the barrier to entry. These are complemented by NVIDIA NIM microservices, which enable developers to easily optimize models for certain hardware architectures. Crucially, these models can operate locally on a researcher’s personal computer, guaranteeing the security of confidential information.

Expanding the Open Model Portfolio
Another significant development in NVIDIA’s larger dedication to open-source AI is the release of Ising. It becomes part of an expanding collection of specialized open models, such as:
- NVIDIA Nemotron (agentic systems)
- NVIDIA Cosmos (physical AI)
- NVIDIA Isaac GR00T (robotics)
- NVIDIA BioNeMo (biomedical research).
The global developer community may now access these models, including the Ising family, on GitHub, Hugging Face, and NVIDIA’s build platform.
AI’s function in controlling the underlying hardware becomes more important than ever as the world gets closer to a “quantum advantage” where quantum machines outperform classical computers on particular activities. NVIDIA is giving the community the “operating system” required to close the gap between theoretical study and real-world, large-scale quantum application with the introduction of Ising.

Expertise Behind the Breakthrough
The development of Ising was led by a diverse team of experts across quantum physics and AI. The project’s authors include Tom Lubowe, a senior product manager with a background in tensor networks, and Christopher Chamberland, a specialist in fault-tolerant QEC who previously held roles at IBM and AWS Quantum. Other key contributors like Shuxiang Cao, Ivan Basov, and Jan Olle brought expertise from institutions such as the University of Oxford and the Max Planck Institute.
This interdisciplinary approach has resulted in a workflow that integrates seamlessly with popular developer tools. Using the NVIDIA NeMo Agent Toolkit, developers can now build autonomous agents that monitor and calibrate quantum systems with minimal human oversight. These agents have already seen successful integration with coding platforms like Cursor and Claude Code.

The Road to Quantum-GPU Supercomputers
By providing the software infrastructure to handle noise at scale, NVIDIA is positioning its GPUs as the essential classical “brain” required to manage quantum “hearts”. The goal is the creation of Quantum-GPU Supercomputers, where the low-latency processing of NVIDIA hardware enables quantum systems to finally tackle useful, real-world problems in chemistry, materials science, and cryptography.
With the release of NVIDIA Ising, the company has not only provided the tools for today’s researchers but has set the standard for how the industry will benchmark and deploy the fault-tolerant quantum systems of tomorrow. Developers can begin exploring these resources today through the NVIDIA NGC Catalog and GitHub.
